# Bounding Box Visualization
### About this block
The Bounding Box Visualization block lets you see the bounding boxes from an Object Detection Model on an image.
The Bounding Box Visualization block.
This block only shows bounding boxes. If you want to see class labels, you will need to add a Label Visualization block.
### What you can send into this block
To use this block, you need:
1. An input image or video frame, and;
2. Predictions from an Object Detection model.
### What this block returns
The Bounding Box Visualization block returns an image with the bounding boxes from an Object Detection model.
Here is an example output from this block:
Predictions from an object detection model displayed on an image.
### Use cases
This block is useful if you want to see the results from a model on an image. This is common during testing.
Because visualizing predictions adds a small amount of overhead to running a Workflow, we only recommend adding a Visualization in production if you need to see the location of results from your model.
